My whole teenage existence and on up (after my mother passed away) I've always had the same dream about her..
The dream usually was pretty simple: She wasn't dead and never died and the tone of the dream went either two ways: I was happy that she was alive or sometimes VERY angry that she lied to me. Obviously whatever emotion I was feeling took the dream to a different level.
My self diagnosis is simple, repressed emotion toward my mothers death.

But last night it went to a whole new level! I had the dream of her being alive, But my family was involved. I also screamed at her, asked her how could she have lied to me and left me to raise myself, my brother and take care of my father. I was going into detail about John and how alone and broken down I felt. My brothers and sisters were trying to protect her, but I kept yelling and throwing things.
My unconscious mind was very upset last night, apparently. There's a definite amount of resentment in the dream, a little PTSD, and the outburst is more signs of repressed emotions.

Man, it was just crazy..I woke up in a sweat andm y heart racing. It's NEVER been that intense or depressing.
